+ This class does not support input files containing multiple streams (such
+ as those produced by the :program:`pbzip2` tool). When reading such an
+ input file, only the first stream will be accessible. If you require
+ support for multi-stream files, consider using the third-party `bz2file
+ module <http://pypi.python.org/pypi/bz2file>`_ instead of this class.
